A teenager trapped on the missing Titanic submarine is a student at Strathclyde University in Glasgow.
Suleman Dawood, 19, is one of five people on board the vessel which disappeared during a dive to the ship wreck - including his businessman father Shahzada, 48.
A university spokesman said they were deeply concerned about the student and the others in the vessel.
In a statement, they said: "We are deeply concerned about Suleman, his father and the others involved in this incident.
"Our thoughts are with their families and loved ones and we continue to hope for a positive outcome."
Labour MSP Pam Duncan-Glancy said her thoughts were with the teenager and his family while speaking at First Minister’s Questions in Holyrood.
She said: “The young man on the Titan submersible is a student in Glasgow.
“I’m sure that everyone here will join me in sharing their thoughts with him and his family at this unprecedented and difficult time.”
A desperate international mission has been underway to try and find the Titan vessel before their four-day oxygen supply ran out.
A US coast guard spokesperson previously said it will run out at exactly 12.08pm UK time today - but no trace has been found.
The craft submerged on Sunday morning before its support vessel lost contact with it about an hour and 45 minutes later, according to the Coast Guard.
It went missing around 435 miles south of St. John’s, Newfoundland, according to Canada’s Joint Rescue Coordination Centre in Halifax, Nova Scotia.
